两个数字比较大小

代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<title>Document</title>
<style>
    *{margin: 0px;padding: 0px;}
    body{font-size: 13px;padding: 100px;}
    input[type=text]{width: 60px;height: 26px;line-height: 26px;background-color: #eee;border: 1px solid #ccc;}
    input[type=button]{padding: 5px 15px;}
    h2{color: red;display: inline-block;}
</style>
<script>
    window.onload=function(){
        var aInput = document.getElementsByTagName('input');
        var oBtn = document.getElementById('btn');
        var oH = document.getElementsByTagName('h2')[0px];

        for(var i=0;i<aInput.length-1;i++){
            aInput[i].onkeyup=function(){
                this.value = this.value.replace(/[^d]/,'');
            }
        }

        oBtn.onclick=function(){
            (aInput[0].value==''||aInput[1].value=='')?
            alert('请输入数字'):
            (oH.innerText = Math.max(aInput[0].value,aInput[1].value));
        }
    }
</script>
</head>
<body>
    <input type="text" />
    <strong>VS</strong>
    <input type="text" />
    <input id="btn" type="button" value="最大数是>>>" />
    <h2></h2>
</body>
</html>

结果如下图所示:

Math.max()方法的使用
